Description

Technical Field

[0001] The present invention belongs to the technical field of anti-collision guardrails, and more specifically, relates to a push-pull opening type bridge anti-collision guardrail and a use method thereof. Background Art

[0002] In bridge engineering, crash barriers play a vital role. They are generally installed on both sides of the roadway to prevent vehicles from deviating from the predetermined trajectory and ensure driving safety. Since vehicles may collide at any position, in order to achieve the best protection effect, crash barriers are usually designed as continuous and uninterrupted structures. However, this continuity becomes an obstacle when bridge maintenance personnel need to cross the guardrail to work. In order to solve this problem, the guardrails at specific locations are designed to be openable to facilitate the passage of personnel and equipment.

[0003] With the increasing attention paid to the convenience of bridge maintenance in China, anti-collision guardrails with various opening modes have appeared on the market, such as flat opening and flip-up types. In the prior art, a Chinese patent with document number CN211775957U discloses an openable edge guardrail, which belongs to the field of building construction technology, and includes a plurality of guardrail monomers connected to each other, wherein at least one guardrail monomer is an openable guardrail, wherein one side of the openable guardrail is fixed to the guardrail monomer adjacent to the side through a bolt assembly, and the other side is hinged and fixed to the side of the guardrail monomer adjacent to the side; the bolt assembly includes a plug ring, a latch and a lock buckle, the plug ring is fixed to the openable guardrail and the adjacent guardrail monomer, the latch is fixed with a lock handle, the lock handle is provided with a lock buckle hole, and the lock buckle is fixed to the guardrail monomer; when the latch is inserted into the plug rings on both sides to lock the two guardrail monomers, the lock buckle hole on the lock handle is connected with the lock buckle to lock the latch. The Chinese patent with the document number CN218293066U discloses an openable anti-collision guardrail, which specifically includes a fixed guardrail and a movable guardrail. The two ends of the movable guardrail are fixedly connected with fixed guardrails. The fixed guardrail is composed of an upper limit rod 1, a lower limit rod 1 and a fixed railing 1. The movable guardrail is composed of an upper limit rod 2, a lower limit rod 2, a fixed railing 2 and a movable railing. The end of the upper limit rod 2 is fixedly connected to the upper limit rod 1, and the end of the lower limit rod 2 is fixedly connected to the lower limit rod 1. The openable anti-collision guardrail is provided with a movable guardrail. The distance between two adjacent movable railings in the movable guardrail can be adjusted according to demand, so that the movable guardrail can be in a closed or open state, which is convenient for the staff to repair the gap between the workpieces protected by the inner side of the guardrail and to use the guardrail.

[0004] Although the above patents enable some guardrail beams to rotate freely in the horizontal or vertical direction through clever designs such as rotating pins, which can greatly improve the efficiency and convenience of bridge maintenance, in actual application, the friction at the rotating pin position is large, which can easily cause locking and affect the opening of the guardrail; secondly, the flat-opening anti-collision guardrail may invade the lane, posing a risk of collision, and the flip-up type needs to overcome gravity, which limits the width of the anti-collision guardrail that can be opened.
